Software optimizations for the GB200 NVL72 have drastically reduced serving costs by 2.5 times in under 70 days. These improvements, particularly the rewriting of the NVFP4 MoE kernel using CuTe-DSL and leveraging the NVL72's high-bandwidth copper backplane, were applied to the Kimi architecture, which also powers xAI's Cursor Composer 2.5. This significant cost reduction highlights the impact of software engineering on AI infrastructure efficiency. AI
